Patented Apr. 14, 1931 i UNITED STATES PATENT OFFICE WAGON-TIPPING APPARATUS Application filed July 19, 1929, Serial No. 379,485, and. in France August 1, 1928.

The present invention provides a wagon tipping apparatus based on a special articu lated system and so designed that the dis charging or emptying operation may be carried out with less motive power than is possible with existing types of such apparatus, the invention being mainly applicable to the common method in which the contents of the wagons are discharged through side doors in the wagon into a silo situated at one side of the permanent way as represented in Fig. 1, and to the method in which ends of the wagons have movable panels articulated on vertical or horizontal axis, instead of side doors, the contents of the wagon being discharged into a silo situated directly underneath the permanent way.

As the second method is rarely employed, and the mechanical system of operation is exactly the same as the first mentioned method, it will be" understood that the annexed drawing will be suificient for both methods.

Fig. 1 is an end view of the tipping apparatus showing the tipped position in dotted lines.

" in accordance with this system and of appropriate dimensions may be used for tipping of several wagons simultaneously.

A further object of this invention is: 1) a simplified arrangement of the levers for supporting the tipping table or platform, (2) simplified type of lever brackets and (3 a new application concerning wagons of the end-tipping or longitudinal type.

In the first object, the ends of the levers B, C as shown in Fig. 4: of the annexed drawing are no longer intercoupled except by means of table member A, and in the second object the brackets HI (shown in Fig. 1) are replaced by a special bracket D as shown in Fig. 4; of the annexed drawing.

In the principal object the apparatus comprises or includes a special device for discharging the contents of the wagons from an end or ends thereof into a silo O situated at one side of the permanent way.

Fig. 4 represents an elevation viewed in the direction of the permanent way, and Fig. 5 is a plan.

As will be seen in Figs. 1 and 2 the metal table member A forms a bridge and registers with the permanent way. Said table rests by means of two sets of shackle members on the ends of two series of levers B, G having two arms, the position, length, and movements of these arms being determined by the calculus and angle following the position of the centre of gravity of one wagon or a series of tipping wagons forming a single unit.

All of said levers B, C are coupled two by two by the rods 1) so as to uniformly function these parts of the apparatus.

The levers B, C receive their movement from rods E the ends of which are anchored to crank pins mounted on the gear wheel F, these wheels being coupled to a reduction motor unit G.

The bearings H, I represent the fixed fulcrum points around which the levers B, C partially rotate in one or the other direction. During the tipping operation the wagons are held on the bridge by the screw stop chocks or brackets J provided with hand wheels K which bring the stop pieces L of the brackets into engagement with the wagon. The apparatus also carries the ordinary automatic stops to hold the wagon in its correct position on the tipping permanent way. These stops with their mechanism are, for the sake of simplicity, not 0 shown in the drawing.

In Figure 5, the wagon has been brought, after partial rotation, into a position at right angles to is normal direction.

In the construction shown in Figures 4 and 5, the table member receiving the wagon is formed of two parts A, F, the lower part A resting by two sets of shackle bearings on the ends of a series of two armed levers B,

and a series of single armed levers C. Said levers B and C oscillate on two axis carried by a set of double bearing brackets D.

The movement is transmitted to the tipper by the rods E coupled on the one part to the levers B and on the other part to the motive mechanism G consisting of a reduction motor and gear wheels, the wheels being pro vided with bearing pins forming the cranks for the rods E.

On the table member A there are fixed two buffer stops L carrying the screw stops M and the hand wheel'N for operating the screw stops, the stops being disposed in alignment with the wagon buffers so, as to serve as holding members for the wagon during the tipping operation.

The'revoluble part F of the table member pivots on a pivot pin H carried by the lower partA of the table member.

The part F of the table member is supported by four rollers I adapted to operate on a circular runway provided partly on the lower part A of the table and partly outside the tipper on the-circular rails J as shown in Fig- 5.

As will be seen the upper part of the table F carries the rails forming the permanent way for the wagons. I

F being a turntable, its movement of rotation is produced by, hand, or automatically by the adoption of any one of the well known electro mechanical methods, as normally used in suchv cases.

The tipping operation is effected in the following manner:

The platform F being placed and scotched .in register with the rails K, a full wagon is The wagon door bolt is now withdrawn, the tipper is set in motion, the wagon tilts as shown by the dotted lines, Fig. 4:) emptles a plane above the bracket connection 9f the first mentioned lever and to the platform adjacent the opposite end, and means for operating the angle lever to thereby compel an upward movement of the platform connected end of such lever while the first men- 'tioned lever is compelling a movement of the platform connected end, the relation of the levers being such that the end of the platform connected to the first mentioned lever moves downward in a substantially straight line, while the end of the platform connected to the second mentioned lever moves upwardly and toward a vertical plane.

In testimony whereof I aifix my signature.
